Health care cannot be the same without the services of hematologists. Many health care practitioners have to call on the help of a haematologist often because many diseases can be diagnosed through testing our blood. A hematologist is a health expert trained in the handling of blood. Most of them will be members of a professional body like the American society of hematology. There is at least one hematologist in any major medical center.
Their work is very important because they offer an easy way to diagnose patients without invasive techniques being employed. Most diseases that are caused by bacteria and viruses can be tested in our blood as well as others like cancer that is not caused by a known parasite. So a hematologist is an important addition to a cancer center.
Hematologists also check treatment to see if they are effective by making blood analyses like in the case of radiation oncology or even HIV treatments where they check for the number of virus in the blood against the white blood cells. They pass this information to the treating doctor who can adjust or stop the treatment depending on what the analysis gives. The hematologist will interpret the results so they make sense even to a non-medically trained person.
Within the profession hematologists can specialize in specific areas to become experts in it like paediatric hematology oncology for someone who enjoys working with and helping children. To keep their skills up to date haematologists attend annual meetings to exchange information with other hematologists.
